But one nasty consequence of the update saw some users reporting that their progress had been reset to level one.

Many shocked fans believed that in downloading the update they had unintentionally reset itself and naturally took to Twitter to kick off and moan at the games developers.

Some went as far to have called for any money spent on Pokémon Go to be refunded while others desperately searched for a way to reverse the change.

One user wrote: "Beware of the #PokemonGO update. I've just lost all of my progress. Everything gone. Level 1 again. Not impressed :("

While another complained directly to the games developers, saying: "Account was deleted by the Pokemon Go update, so I am now a level 1 instead of level 19. Might be time to quit lol @NianticLabs"

However, all is not lost it seems.

Users have simply logged in with the wrong email, because during the update, the games developers updated its Google account login system.

Because of this Niantic say players "may have inadvertently created another 'Pokemon Go' account by logging in with a different Google email address than the one originally used for the game."

"Please be assured that your gameplay progress has NOT been lost. It remains safe and intact," the company wrote.

To fix the problem, Niantic has advised that any angry Pokemon trainers who've been reset back to level 1 - who may have "inadvertently" created a new account - to uninstall the game and then reinstall it.

In doing so, they then ask that log back in with the original email address they used when they first registered.

This will then ensure that you return back to your character, at whatever level you left it at.
